This is rather weird repair, but I don't like to give up when diagnosis is clear.
Dumb customer put too long screws in VESA support holes. He broke inner female holders and damaged some SMD components in MAIN board. I see two tiny SMD MLCC unsoldered, but my main concern is that crystal X200 is broken and missing top cover. It's a very small SMD crystal, 4 contacts. I haven't found this cover inside TV, it possibly fell through bottom ventilation grid. Main IC is a XD Engine LGE6352, IC101.
I can't find schematic of this quite new TV, so I'm in need of knowing which frequency is this crystal. 12MHz? 24MHz? Other? I'll wire a larger crystal if I have it, I wont bother to get the same one, just need the frequency. Thanks.
EDIT:
I've searched other models with same main IC LGE6352. I've found some pictures of a 49" but the crystal number is unreadable, but... I attach largest picture I've found. I can barely read 24... at X101, so I've tried with a 24MHz large crystal. It works! I've glued it to the board and soldered two thin wires.
